ROLLER SIDE Bi'iAnIiiG. l

ToaZZ whom i'tmag concern." i

Be it known that 1, JOHN F. OConNoR, av citizen of the United States, residing at Chicago, in the county of Cool; and'State of Illinois, have invented acert'ain new and useful Improvement in Roller Side Bearings, of which the following is a tulhclear, concise, and exact descriptionpreterence being had to the accompanying drawings forming a partof this specification,

This invention relates to improvements in roller side bearings,

One object of theinvention is to provide a simple, relatively cheap roller side bearing for railway cars and'so arranged that the roller will be automatically returned to central or normal position after'each actua tion. I

Another and more specific object otthe invention is to provide a spring controlled, roller side bearing wherein the roller is re-,

turned to normal after actuation, by a come with. Fig. 2 is a horizontal sectional View, upon an enlarged scale, of the improved" side bearing proper. Fig. 3 is a longitudinal, vertical section of the structure illustrated in Fig. 2 and taken on the line 33 thereof. Fig. 4 is a detailed sectional view taken substantially on the line 4 4 of Fig. 2. And Fig. 5 is a perspective view of the spring attaching block employed.

In said drawing, 10 denotes the body bolster and 11 the truck bolster which are pivotally connected at their centers in the usual manner. As shown, the body bolster is provided with a striking plate 12 and the truck bolster has applied thereto the improved side bearing designated generally by the reference A.

The improved side bearing A preferably comprises a base member or casting B which is riveted or otherwise suitably secured to the truck bolster, and an anti-friction roller C. The base member B is of substantially box-like form, open at the top and has outwardly extended bottom flanges 13 through which pass the securing means, and on its interior, the base member is provided with a suitable in'serted'tread or wear plate '14 on which the'roller operates.

Specification of Letters Patent. Appiieationfiiee ulyis, 19 1' s1=a1m.109,016. Q

The base plate or retaining member '13 is provided withsi'de walls 15 and 16, and end walls 1'Z 17, the latter being outwardly conve'xed as indicated at 18 18 in Fig. 3. The roller C is provided with a central opening 19 which is flared at one end as indicated at 20. At the opposite end, the opening'19 'is made of rectangular form as indicated at and has fittedtlierewith'in a spring re taming block The -,latt'er'is recessed on its inner, face as indicated at 23-,"to receive the end of the spring 24. WVithin said recess, the block 22 is provided with a pai of spaced lugs 2525, over which fit the coils ofthe spring andb'etween which 8X? tends the bent end 26 of'the spring so that relative turning movement between 'the spring and the roller C is prevented The side wall 15 of the base casting orro'ller retaining member is providedwi'th a hollow offset boss 27 which is flared-as indicated V extends the'bent end ofthe' spring, thus preventing rotation of the spring with respect to the said boss 27.

As the roller C is actuated, it is apparent that it will be moved to one side or the other and in so doing, the spring 24 will be flexed or bent as an entirety, this movement being accommodated by the flared openings 20 and 28. In addition to said bending of the spring 24, it is apparent that the spring will be twisted. hen the roller is moved to one side, this additional twist or torsion will be in the same direction as the inherent twist of the spring and when moved in the opposite direction, the twist or torsion created will be opposed to the inherent twist of the spring. In either direction, the torsional effect thus created will assist in more certainly returning the roller to normal or central position. It will be understood that the roller C is limited in its movements by the end walls 1717.

From the preceding description, it will be seen that I have provided a roller side bearing which may be relatively cheaply manufactured; wherein is employed a roller of comparatively large diameter presenting a wide bearing surface; and wherein the roller is always returned automatically to casting, the roller being provided with a cennormal position after, each". actuation.

I claim:

1. In a roller side bearing, the combination with a retaining member, and a'roller bodily movable therein, of means for returningisaid roller to normal position after actuation thereof, said means comprising, a, spring extending between said member and the roller, said spring being, non-,rotatably secured to saidmember and the roller, whereby the end of saidspring which is attached to the roller, is rotated in unison with the rotation of the roller.

2. In a roller side bearing, the combination. with a retaining member, and a roller bodily movable therein, of means for returning said roller to normal position after actuation thereof, said means comprising, a spring 'non-rotatably secured to said'memher at one end, the other end of said spring being extended into the roller axially thereof, the end of the spring within the roller being also non-rotatably secured to the roller;

3. In a roller side bearing, the combination with a retaining member, and a roller bodily movable therein, of means for returning said roller to normal position after actuation thereof, said means comprising, a

spring secured at one end to said. member and atvits other end to the roller, said member and said roller being each provided with normally alined openings into which the ends of the spring extend.

4. In a roller side bearing, the combination with a hollow base casting, one of the walls thereof being provided with a hollow boss, of a roller mounted within saidbase trally located recess normally al'ined with said hollow boss, and a spring having its "ends extended into said hollow boss and the recess in said roller, the ends of said spring being fixed with respect to the hollow boss and said roller,respectively.

5. In'a roller side bearing, the combination with a hollow base casting having a flared opening in one of it'swalls, of a roller mounted within said. base casting, the roller having a centrally located recess which is flared toward said flared opening in the base casting, and a spring having its ends extended into said opening and attached at its ends respectively to the base casting and said roller.

6. In a roller side bearing, the combination with a base casting, of a roller, a spring extending between said base casting and roller, and means for non-rotatably securing one end of said spring to the roller, said means comprising,- a block of non-circular form mounted in a correspondingly shaped recess in the roller, said block being provided with a pair of spaced lugs over which the end of the spring fits and between which the extreme bent end of the spring-is located. In witness that I claim the foregoing I have hereunto subscribed my name this 11th day of July, 1916.
